Formalization of the user centric SOA approach: Implementation and end user satisfaction evaluation

User-centric SOA is a new paradigm allowing unskilled end users to compose services to create new one. Mashups represent new agile and quick ways to compose and integrate structured and unstructured resources, from different types existing on the web. Mashups emerged as a new way to democratize the SOA and realize the user-centric SOA; However, Mashups are emerging applications, and thus consist of immature, non intuitive and non formalized area. In this paper, we formalize the user-centric SOA development by proposing a new cloud-based architecture for user-centric SOA platforms, and by introducing a new rich integration language based on the advanced Enterprise Integration Patterns (EIPS). We also propose a new intuitive and self-explanatory semantic methodology and interaction model for end users services integration. Through these contributions, we give the promise of realizing the user-centric SOA.
